eli5: Why geothermal energy is not very efficent? If we dug much Much deeper could we gather massive amounts of energy because of being closer to the core? (I saw how close we are currently to it so I don’t think its happening anytime soon)
In: Earth Science
Could you elaborate on to what you are referring? Geothermal heating with heatpumps is **incredibly** efficient. Costs are significant because digging holes isn’t cheap, but you’ll habe trouble finding a way of heating (and cooling for that matter!) a home more energy-efficiently than with a geothermal heatpump.
I guess if you actually wanted to run a *generator* with geothermal heat your plans are limited by whether you live near a tectonic fault or not – you’d need a volcanic vent.
